Razorpay Interview Questions (13)

Razorpay is one of India's fastest-growing fintech companies, and its engineering team focuses heavily on building scalable, reliable payment infrastructure. Because their products handle millions of transactions, Razorpay places strong emphasis on candidates who can write efficient code, reason about edge cases, and design systems that scale.

The Razorpay coding interview typically evaluates core data structures and algorithms along with practical problem-solving skills. Candidates are expected to be comfortable with common DSA patterns and write clean, production-ready code during interviews.

Based on real interview experiences, Razorpay interview questions frequently test:

• Arrays and hashing for transaction-like data processing
• Sliding window and two pointers for optimization problems
• Trees and graphs for hierarchical or dependency modeling
• Dynamic programming for optimization scenarios
• Stacks and queues for stream-style data handling

The difficulty distribution usually includes a mix of medium and hard problems, with interviewers focusing more on how you approach the problem rather than just arriving at the final solution.

On this page, we’ve compiled 13 real Razorpay coding interview questions asked in previous interviews. Each problem is organized by difficulty and includes solutions in multiple languages to help you practice effectively.

FleetCode helps you prepare the same way top candidates do: by practicing company-specific questions, understanding common patterns, and building the confidence needed to perform well in Razorpay's technical interview rounds.

Preparing for a Razorpay coding interview requires a strong grasp of data structures, clean coding practices, and the ability to reason about performance. Since Razorpay builds high-scale financial infrastructure, interviewers care deeply about efficiency, reliability, and edge-case handling.

Typical Razorpay Interview Process

• Online coding assessment: Usually 2–3 DSA problems to solve within 60–90 minutes.
• Technical interview rounds (2–3 rounds): Live coding with a focus on data structures and algorithms. Expect medium to hard problems.
• System design or machine coding round: For experienced roles, candidates may be asked to design scalable services or implement a simplified system.
• Hiring manager or culture round: Focuses on past projects, problem-solving mindset, and collaboration.

Most Common DSA Topics Asked at Razorpay

• Hash maps and arrays for transaction-like data manipulation
• Sliding window and two pointers for performance optimization
• Trees and graph traversal problems
• Stack-based problems and monotonic stacks
• Dynamic programming for optimization challenges

Preparation Strategy

• Focus on solving medium-level problems quickly and cleanly. Razorpay interviewers often test implementation quality.
• Practice explaining your thought process while coding.
• Optimize brute-force solutions step by step to reach optimal complexity.
• Review time and space complexity for every solution.

Common Mistakes to Avoid

• Jumping straight into coding without clarifying constraints
• Ignoring edge cases such as empty inputs or duplicates
• Writing code that works but has poor complexity
• Not testing your solution with example inputs

Recommended Preparation Timeline

Most candidates preparing for Razorpay spend around 6–8 weeks practicing DSA. Aim to solve 150–200 structured problems and include company-specific practice sets like this one to understand the patterns Razorpay interviewers commonly test.
